DIE FOR CUTTING PAPER, SLC.

SPECIFICATION forming part; of Letters Patent No. 348,548, datedSeptember 7, 1886.

Application filed March 20, 1886. Serial No. 195,933. (No model.) V

T0 @ZZ whom it may concern:

Be it known that I, SAMUEL CRUMP, a citizen of the United States, andresident ofMont clair, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in DiesforCuttingPaper, die., of which the following is a specification.

My invention relates to an improvement in dies for cutting paper orother material, the object being to provide a die which will at oneoperation cut the material, half cut the same ou certain lines, andscore `it on others, on which it is to be folded in forming a box orother article.

A further object of my invention isto construct a die of practically onepiece, and obviate the necesssity of forming separate blocks wherewithto hold the several sections of the cutting-knives and scoring-piecestogether.

A further object of my invention is to provide a die which shall besimple and economical in construction, capable of being easily andreadily formed, and which shall be durable and eflcient in use; andwithsuch ends in view my invention consists in certain novel features ofconstruction, as will be hereinafter described, and pointed ont in theclaims.

In the accompanyingdrawings, Figure l is a top plan view of my improveddie. Fig. 2 is asectional view thereof on the line ab of Fig. 1. 3 is atop plan view of the templet.

For the sake of illustration I will describe my invention constructed tocnt blanks for paper boxes; but I would have it understood that I innowise limit my invention to such appli cation, as dies construct-ediliaccordance with my improvement might be used for cutting veneers,labels, showcards, placques, 85e.

Referring to the drawings, A represents the base-plate of the die, onwhich rest the cutting-wires B, arranged to impart to the material beingcut the proper outline. On the plate A also rest the cutting-wires C,the edges of which are located in a plane somewhat below that of theedges B, the'purpose of the cutting-wires C being to partially cutthrough the material of which the blank is formed on Vcertainlines onwhich the box is to be folded.

These cutting-wires B C are preferably made of hardened steel, in orderto prevent losing their sharpened edges when they come in contact withthe metallic plate on which the material being cut rests.

I) represents brass wires arranged to score the blank on the lines onwhich it is to be folded, the upper edges of these wires being locatedin about the same plane as that of the Wires C.

Upon the surface of theylt A is a coating of metal, Acelluloidor othermaterial-serving to hold the cutting and scoring wires in po sition onthe plate, the saidmetal or Celluloid serving as an anchorage for thewires, and also practically forms the die of one piece. This arrangementI have found far superior to the ordinary cutting-dies, which havegenerally been constructed of metal blades arranged in accordance withthe outline to be given the blank and the brass scoring-rods all held intheir proper relative positions by blocks, the whole being set upsimilar to a form of type and then bound or locked together.l It is veryevident that the construction of this form of die involves a greatexpenditure of time and labor-as, for instance, in constructing a die ofthe Vform shownin the drawings-it was first necessary to arrange themetal blades similar to the wires B and C, then the scoring-pieces D,and then to form blocks to lit in between the blades and scoring-pieces.

It will be readily seen that to form blocks similar in contour to thepolygon a, the triangle I), the triangle c, quadrilateral d, die., inorder to hold the blades in position added materially to the cost andtime of producing the die, and that by myimproved device theseobjections are entirely overcome.

In forming my improved die Ifust construct the templet E, which consistsof a plate having grooves formed therein for the reception of thecutting and scoring wires, the grooves being formed to hold the wires inpositions to impart to the blank the proper outline. In cutting thesegrooves, which is preferably done by a ruling-machine, care should betaken to form them of proper depths,the grooves f, for

the reception of the cutting-wires B, being of such depths as to receivewires slightly thicker than the material of which the blank is made, andthe grooves g, for the reception of the wires G, being of such depth asto receive wires of such thickness as will partially cut through IOC thematerial. The cutting and scoring wires are placed Within theirrespective grooves and a coating of metal, Celluloid, or other suitablesubstance spread over the templet and Wires, the sharp edges of whichnlatter are turned downwardly, the surface of the templet being rstcoated,.if necessary, with a suitable ma teriahas soapstone orplumbago,to prevent'the metal from adhering thereto. The upper edges ofthe groove formed in the templet are beveled, for the purpose ofallowing the metal or celluloid or other substance to partially en.-

Y ter the groovcs-and take a iirm hold of the Wires. A plate, A, is thenplaced on the layer or coating A, and the Whole subjected to heat andpressure, either orboth, according to the material of which the coatingis composed un- `til said coating has entered the grooves and graspedthe Wires, and also taken hold of the plate A. After this operation thedie is allowed to cool and `then raised from the templet, the scoringand cutting wires having their baseedgesqemledcled in the substance ofWhich the anchorage is cmposedrgnd by virtue thereof held firmly to thebaseYpiate,-,and,having scraped away the excess of metal, if any, fromaround the cutting-wires, the die is ready for.

use.

It will now be seen from the above description that my improved die canbe constructed much quicker and much cheaper than ordinary dies used forthe same purpose, and is not so liable to get out of order, as theanchorage of metal or other material forming one piece with the plateand Wire is more effective in holding the latter in position than theblocks heretofore describe( Several of these dies may be usedconjunctively, and a corresponding number of blanks cut from a sheet ofmaterial at one operation, the edges of the cutting-Wire beingpreferably provided with a notch or notches to prevent said blanks frombeing entirely severed from the sheet of material.

I do not Wish to have it understood that I in anyWise limit lnysel` toany particular metal or substance for forming the anchorage of theWires, as I might use any of the metals, celluloid, or other substances,butin forming my improved die I would recommend the use of thecomposition described in the patent granted to me, assignee, No.336,590, and dated February 23, 1856, which may be spread on the templetin a powdered form, and by the aid of heat and pressure be transformedinto a solid metal; nor do I Wish it understood that I make any claim inthis application to the method of forming my improved die, as I reserveunto myself the ri ghtto make such the subject matter of a separateapplication.

That I claim as my invention, -and desire to secure by Letters Patent,is-` l. A die for cutting paper or other material, constructed ofcutting-Wires arranged in proper relative positions, having theirbaseedges embedded in a plastic substa-nce hardcned to form a solidanchorage for the wires, substantially as set forth. Y

2. A die fofcutting paper and other material, constructed of abase-plate, scoring and cutting wires arranged in suitable relativepositions, and a coating or anchorage attaching itself to the base-plateand embedding the base-edges of the wires and securing them in position,substantially as described.
